Model C10

IntroductionThank you for purchasing this VEE GEE Refractometer. With the user in mind, VEE GEE Refractometers are built from moderndesigns and, with proper care, this instrument should provide many years of reliable performance. It’s recommended thismanual is read entirely before using the refratometer for the first time.VEE GEE Model C10 Abbe Refractometer is designed to measure the refractive index (nD) values of transparent and translucentliquids and solids. A constant temperature circulator can be attached to this instrument to stabilize refractive index readingsand add to the instrument’s accuracy and reproducibility. The temperature range should be kept between 0°C and 70°C.Measuring refractive index values is useful for many types of applications. Since every transparent and translucent liquid andsolid has a specific refractive index, the instrument can be used for identification, to check purity, etc. The Brix scale can beused for measuring the concentration of water soluble solutions such as salt, sucrose, urine, oils, sugar, etc.Abbe Refractometers are often used as the standard for checking handheld refractometers and results from other types ofinstruments because of its consistent and reliable results.InspectionUpon receiving your VEE GEE Model C10 Abbe Refractometer, check to see that all parts are functioning and focusingproperly and that the following items are supplied with your instrument:1. Thermometer w/ Protective Shield (1 ea.)2. Glass Standard (1 ea.)3. Bromonaphthalene, ¼ oz. Bottle (1 ea.)4. Calibration Screwdriver (1 ea.)5. Operation Manual (1 ea.)PrecautionsThis refractometer is an optical instrument. Do not shake or jolt the instrument. The impact may damage or cause theoptical components to shift which will result in inaccurate readings.The prism is made of optical glass and is susceptible to scratches -- do not apply any rough or abrasive material and takecare when cleaning the prism.After each use, clean the primary prism surface (and secondary prism, if needed) with a soft cloth or tissue soaked inwater and wipe off with a dry cloth or tissue.Do not hold the refractometer under a stream of water from a faucet. Do not splash it with or dip it in water.If the surface of the prism becomes coated with an oily solution or similar, it will repel test samples and affect readings.If this occurs, the prism should be cleaned with a weakened detergent or similar solvent.Keep the instrument in a dry, well-ventilated room.2 7http://www.novatech-usa.com/Products/Laboratory-Equipment-Supply-Products Tel: (281) 359-8538 Toll Free:(866) 433-6682
